I switched from 50mcg of Levo and 10mcg of Liothyronine a few months ago to Nature-throid. I have done this without Gp or Endos knowledge. I started on 1/2 grain and got to 1 grain am and 1/2 grain pm and then could raise no higher. Started getting really bad headaches, fatigue and high anxiety. Dropped dose back down and tried to raise slowly again supporting my adrenals with Nutri adrenal and iron Spatone. Now feel terrible still even on a small amount of ndt. Feel like I'm going hyper bit recent bloods showed T3 ok. T4 still low and Tsh suppressed (-15) so pretty suppressed. What can I do? I don't know what to take Levo, T3 or ndt? Even a small amount seems to be making me freak out atm.
